Dave,
I pretty much did as you stated. I used a 4" piece of floor shoe (3/4" quarter round) as my sanding block and worked things until they were relatively smooth and level. I even used a Craftsman version of a Dremel tool to grind a small groove that the gelcoat could better flow into since the residual dark area was almost hairline. That worked pretty well but it thinned out in another spot right on the edge. You can't see it unless you are looking up from below the rub rail so I'll take you advice and fight that battle another day.
Don Sr.,
I probably didn't feather things as well as I should have but there are a couple of tiny depressions that I can use a small artist's brush on to feather the gelcoat away from and that might get things closer to perfection.
